Why Choose the Mersen A211508 DIIGG50V20 DIN D Fuse-Link?
The Mersen A211508 is a dependable DIN D fuse-link designed to protect cables, power lines and low-voltage electrical equipment against overloads and short-circuit currents. Identified by the manufacturer reference DIIGG50V20, this fuse-link has a 20 A current rating and a general-purpose gG operating characteristic.
Designed for the established Diazed screw-fuse system, the A211508 uses the standard DII fuse size and blue current-rating identification. Its ceramic body provides effective electrical insulation and thermal durability, while the fuse element interrupts excessive current before cables or connected equipment sustain serious damage.
With voltage ratings of 500 V AC and 500 V DC, the Mersen A211508 is suitable for industrial and commercial low-voltage distribution equipment. It can be installed in compatible DII fuse bases using the correctly rated gauge component and screw cap, providing reliable protection in distribution boards, switchgear and machinery control systems.

Reliable Protection for DIN D Electrical Systems
DIN D fuse-links protect electrical circuits by melting their internal fuse element when current exceeds a safe level. This disconnects the affected circuit and limits the damaging thermal and dynamic effects associated with overloads and high short-circuit currents.
The gG characteristic of the Mersen A211508 provides full-range protection for cables and conductors. When installed with the correct DII fuse base, gauge ring and screw cap, it offers a straightforward and proven circuit-protection solution for existing Diazed electrical systems.
Typical Applications
- Low-voltage electrical distribution boards.
- Industrial switchgear assemblies.
- Cable and power-line protection.
- Commercial building electrical systems.
- Machinery and automation control panels.
- DII Diazed screw-fuse installations.
